对比和分析了前人对陕北黄土高原植被的研究成果后认为陕北黄土高原的阔叶栎林为主的森林界限截止于渭北黄土高原北部,即陇县、彬县、宜君、铜川、黄龙一线。经过植被破坏和土壤侵蚀后土壤基质已经严重旱化和贫瘠化,通过重建植被土壤基质是可以逐步恢复的。植被的重建应该首选择先锋植物种类,造林后应及时进行改造,使其向接近该区天然林(植被)的方向发展,并需要建立一套可持续的森林经营体系。
After comparing and analyzing the previous research results on the vegetation in the Loess Plateau in northern Shaanxi, it is concluded that the broad-leaved Quercus mongolica-dominated forest boundaries in the Loess Plateau of North Shaanxi are at the northern part of Loess Plateau, namely Longxian, Binxian, Yijun, Tongchuan , Huanglong line. After the destruction of vegetation and soil erosion, the soil matrix has been severely weathered and impoverished, and the soil matrix can be gradually restored by rebuilding the vegetation. The reconstruction of vegetation should be the first choice of pioneer plant species, afforestation should be promptly transformed to make it close to the area of natural forest (vegetation) direction, and the need to establish a sustainable forest management system.
